Specification of Letters Patent.

Application filed June 6, 1919, Serial No 302,261.

- Patented May 1920.

To all whom it may concern:

Be it known that 1, Jon Knirrxsxis, a

and useful Improvements in W heelbar rows; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to an improved wheelbarrow and the object thereofis to so improve the construction of the wheelbarrow as to obviate thenecessity of a person wheeling the same carrying the main part of theload or bearing the burden thereof; to strengthen the construction ofthe wheelbarrow so as to permit it to better withstand rough usage; tofacilitate turning or steering and to facilitate dumping withoutinjuring the front supporting wheel, the device in its preferredembodiment being movable on three wheels.

With the. above objects and others in view as will appear as thespecification proceeds,- the invention comprises certain novelcombinations and arrangements of parts as will be hereinafter moreparticularly pointed out and claimed.

Reference is had to the accompanying drawings forming a part of thisapplication, wherein like characters designate corresponding partsthroughout the several views in which- Figure 1 is a side elevation ofmy improved wheelbarrow,

Fig. 2 is a plan view with the body re moved,

Fig. 3 is a detail longitudinal sectional view, and

Fig. 4 is a detailed transverse sectional view.

Referring to the drawings in detail, my improved wheelbarrow is shown ascomprising a body 10 and handle bars 11 preferably made up of a sectionof pipe bent upon itself so that the bight portion 12 is disposed at thefront end. The body 10 is secured to the side or handle bars 11 and forthis purpose, there is secured against the bottom of the body at thefront and back portions of the bottom thereof, transverse strips 13which are bolted through the bottom as shown at 14. The ends of thesestrips are bent downwardly and inwardly in spaced relation to theintermediate portions so as to envelop the sides or handle bars,clampingmeans in the form of bolts 15-being disposed to con nect the spacedportions of the strips adjacent to the side bars so as to preventshifting of one with respect to the other.

. Also secured by the clamping means 15 beneath the inwardly directedportions 16 are longitudinal bearing portions 17 which may be of aslight resilient nature, the latter having depending portions 18 towhich. an axle 19 is rigidly secured as shown at 20. lVh'eels 21 arejournaled on the spindle ends of the axle so as to bear the weight ofthe load contained in the body instead of necessitating that theoperator bear the burden thereof. Extending contiguously with thebearing portions 17 are the rear ends of a substantially circular frame22 suitably bolted or otherwise secured at its rear ends and connectedby a cross brace 23. This frame extends for wardly of the body and iscurved slightly upwardly at its forward end while in order to brace saidframe to the front of the body, there is disposed a U-shaped brace- 24bolted intermediately as shown at 25 to the inclined front portion ofthe body and having the extremities thereof bolted or otherwise securedto the frame as shown Extending longitudinally between the bearingportion 17 and connected to the cross brace 23 is a reinforcing springand brace 27 curved downwardly adjacent to the bight portion 12 as shownat 28 and then connected to the securing means 26, while the free endthereof is curved downwardly and bent to provide a downwardly inclinedU-shaped bearing 29 which receives in conjunction with the forwardportion of the frame 22, a pivot 30 correspond ingly inclined. Betweenthe forward portion of the frame 22 and the bottom portion of thebearing 29 is received a bearing block 31 mounted on the pivot 30 andhaving a fork 82 in which is journaled a wheel 33 forwardly of the bightportion 12 so as to sustain the load in connection with the rear wheels21 and to facilitate steering of the wheelbarrow in either direction.The steering operation is effected preferably by tilting the wheelbarrowin the direction in which it is desired to turn, whence the steeringwheel 33 will lag in the opposite direction due to the pivoting of itsbearing, thus causing the wheelbarrow to turn. Also, the frame 22facilitates dumping as the Wheelbarrow may be rolled on'the frame whentilted on end or to either side,

for dumping the load from the body or scoop thereof,'without injury tothe steering Wheel. It will also be obvious that a considerably greaterload can be carried without unnecessary burden on the operator, byreason of the three-wheel support arranged as described.

What is claimed is 1-- v r l. A wheelbarrow comprising scoop body,handle bars comprising -a single section, of material bent upon itselfbeneath said body, strips bolted to thebottom of the body and having theends thereof bent beneath said bars, clamping means connecting said endswith the intermediate portions of the strips, bearings beneath said barsand strips, an axle supported by said bearings at the rear portion ofthe body, wheels on said axle, a frame having a circular forwardportionand rear extremities in aline portion of said bearing block for movementwithin the frame. 7

2. A wheelbarrow comprising a body, handle-bars comprising a singlesection of material bentupon itself to meet the body, means connectingthe receptacle with the handle bars, a wheel-carrying axle extendingtransversely beneath the handle bars, a frame having a circular forwardportion and rear extremities secured beneath the handle bars, a crossbrace connecting the rear extremities of the frame, a transverse braceextending across the head portion of the frame and arched upwardly forengage ment with said body, a longitudinally extending bracing striphaving its rear end connected with the cross brace and carried forwardlyand arched upwardly for engagement vwith the arch brace and having itsforward end portion connected with the head and bent to provide abearing, a block pivotally mounted in the bearing, and a wheelcarried'by the block.

3. A wheelbarrow comprising abody, a supporting frame for the bodyincluding spaced side bars, a wheel-carrying axle extending transverselybeneath the supporting frame, an open head positioned in front of saidframe and havingarms extending rearwardly' and connected with the bodysupporting frame, a bracing arch extending transversely of the head andengaging said head, a longitudinally extending bracing arch reinforcingthe transversely extending arch and having its forward end portion bentto provide a bearing extending beneath the head, a block pivotallymounted in the bearing for lateral pivotal movement, and a supportingwheeljournaled in the rear portion of the block.
